When I try to copy a CD 'on the fly' using Nero, Windows Media Player automatically loads and starts ripping tracks, and takes ages to stop when I tell it. On WMP I have 'Rip CD when inserted' unselected but it still goes ahead and eventually crashes, sometimes even causing Nero to crash. How can I disable Media Player from doing this? I still want to use it but when I want.
Running on XP.
Thanks
